Michael Flynn resigned his position of national security adviser on Feb. 13 in the wake of reports that he had misled Vice President Mike Pence and other White House officials about his contacts with Russia.
After days of denying the reports, then eventually saying that he was not sure if he discussed sanctions against Russia with Russian officials, Flynn finally said that discussions of sanctions "may have come up" during several calls with the Russian ambassador. The calls were made before Donald Trump was sworn in as president.
In April, the inspector general of the Department of Defense opened an investigation into whether Flynn reported money he received for a speaking appearance in Russia in 2015.
Flynn is alleged to have taken $45,000 for speaking at an engagement in Russia in 2015.
When the investigation was opened, Rep. Elijah Cummings, (D-Maryland), the ranking member of the House Oversight Committee, released letters from the Defense Intelligence Agency – an agency Flynn once headed -- stating that they found no record that Flynn had sought permission to speak in Russia, nor had he reported income from that speech.
A U.S. official, which Flynn as a retired military officer would be considered, must both seek permission and report income derived from any activity with a foreign government.
In 2014, Flynn reportedly received a warning from the DIA about receiving payments from foreign governments without congressional approval.
On Monday (Oct. 30) special counsel Robert Mueller announced indictments against former Trump campaign chairman Paul Manafort and associate Rick Gates on charges of conspiracy against the United States, being an unregistered foreign agent, money laundering, and failing to file reports of foreign bank and accounts.
Earlier in the month, Campaign volunteer George Papadopoulos pled guilty to lying to the FBI as part of a cooperation agreement with Mueller. Papadopoulos was arrested in July.
